Centre to set up a certification authority for calibration of pollution measuring instruments: The Times of India

“NEW DELHI: Noting that the absence of standardised pollution-measuring instruments has sometimes led to inaccurate air and water pollution data, the Centre has decided to set up a certification authority for calibration of all such equipments in the country. At present, different agencies use non-calibrated instruments at different measuring stations and this has led to variation in collected data.” The Times of India
